As it was, the 9/11 Commission was not informed of any investigation of Mr. Berger's alleged tampering with documents until only two days before his testimony, and then in only the most vague terms. Not only were the 9/11 Commission not told that Mr. Berger had access to original documents; they were affirmatively led to believe that the commission got all the documents that Mr. Berger took. Both Mr. Zelikow and Mr. Marcus understood Justice to mean that there was no way Mr. Berger had taken any other documents. An investigator for the House Oversight and Government Reform Committee bluntly told Fox News last week: "The Justice Department lied to the 9/11 Commission about Sandy Berger. That is a fact." A Justice Department spokesman still insists it "has no evidence that Sandy Berger's actions deprived the 9/11 Commission of documents." But that raises the question: How hard did Justice look for such evidence?
